The Blues solidified their depth on the blue line, signing veteran defenseman Nate Prosser to a two-year contract.
The Blues have yet to announce the signing, but Prosser's agent, Ben Hankinson, confirmed in a tweet that Prosser was headed to St. Louis. Prosser was with the Blues very briefly during training camp in 2014 after signing a one-year, two-way contract.
Terms of the contract were undisclosed.
Prosser, 31, is a veteran of eight NHL seasons, all with the Wild. He will be reunited with former Wild coach Mike Yeo.
Prosser has played in 302 NHL regular-season and postseason games. He has seven goals and 31 assists in 282 regular-season games and another two assists in 20 Stanley Cup Playoff games.
Prosser's addition gives the Blues seven veteran defensemen and 23 rostered players under contract.
